I searched this forum for a post with a similar problem, but didnt find anything.

Here is my problem: My Multiface works in disconnect mode, as long as the PC is powered on. DSP Settings says "Disconnected" and TotalMix sliders dont change volume level. When I then disable the "Disconnect" checkbox, the sliders work again. At both times audio is routed, and everything is as expected.But when I'm in "Disconnect" mode and I shut down my PC - as soon as the PC power supply turns off, the Multiface host LED starts blinking and audio is not routed anymore.

I did some tests:- As soon as there is power from the PC, the Multiface works. So even when I enter the BIOS, it works (I was looking if there was a way to keep power on the PCIe bus..)- The Multiface doesnt work when I disconnect the power supply (nothing blinks, no signal)- The Multiface doesnt work when I disconnect the Firewire cable (HOST blinks)

Hardware: Multiface 2 with Firmware 20 and Driver 4.29 using a PCIe HDSPe Card. Power Supply is 12VDC, 2A.I am using Windows 10, if that matters..
